SUMMARY – SURVEY OF MAIZE AREAS AND VOLUMES

SUMMARY – SURVEY OF MAIZE AREAS AND VOLUMES – JUNE 1, 2015

maizer
The objective of this AIMI survey of maize growers was to determine:
 the size of the 2015 harvest of maize grain and maize silage
 the percentage of the 2015 maize harvest which was sold as at June 1, 2015
 the sowing intentions for the spring of 2015
The data from 82 survey farms as at June 1, 2015 were scaled up to the national level using the most recent Agricultural Production Statistics for maize grain and including an estimate of maize seed sales for maize silage. As with all surveys, there is a margin of error which needs to be considered in relation to this report. These figures reflect the position at the 1st June 2015 and there will have been changes since this time.
At the 1st June 2015:
 Average yields of maize grain (10.5 t/ha) and maize silage (20.0 t DM/ha) for the 2015 harvest were very similar to last season (at 11.0 t/ha and 20.8 t DM/ha respectively).
 The maize grain harvest was 74% complete as at June 1, 2015. The estimated total tonnage of 191,000 tonnes (including unharvested grain) was down 19% compared to last season’s harvest. About 82% of the total crop had been sold, leaving 35,000 tonnes unsold as at June 1, 2015 (as compared to 24,000 tonnes at the same time last year). Spring 2015 sowing intentions as at June 1, 2015 were an estimated 5% up on last season, not including data from survey growers who were uncertain as to their intentions because of the importation of maize grain.
 The maize silage harvest was 100% complete on all surveyed farms. The estimated total tonnage of 1,362,000 tonnes DM was up 1% compared to last season’s harvest. About 66% of the total crop had been sold or used, leaving 458,000 tonnes DM unused /unsold as at June 1, 2015 (as compared to 387,000 tonnes DM at the same time last year). Spring 2015 sowing intentions as at June 1, 2015 were markedly down (24% down) on last season.
Table 1. Detailed estimated national figures for the 2015 harvest, plus sold tonnages, for maize grain
and maize silage as at June 1, 2015.
In Table 1 above, the estimated 2015 harvest tonnes of maize grain were 19% lower than for the
2014 harvest. For maize silage, harvest tonnes were similar between the last two seasons.
Table 2. Maize sowing intentions as at June 1, 2015, in comparison with previous years’ estimates.
As at 1 June 2015, maize grain sowing intentions for 2015/16 were similar to last season (5% up). This
is based upon a sample of 25 maize grain growers. There were an additional five growers who
expressed displeasure at the importation of maize grain, and were unsure whether they would sow or
not (the intentions of these growers were taken to be zero).
For maize silage, sowing intentions were markedly down on last season (24% down).
